Hi, the picture quality is not really good (in my use case). I use the program to upscale a fullhd video. In the output you can see very clearly that the frames are decomposed into subframes, upscaled individually and then stiched back together. There is a visible border between the subframes. It almost looks like a grid has been put over the video. Is there a setting to improve this? So far I have tested RealESRGANx4_70% and RealESR_Gx4_70%
Hi my friend, this happens when frames can t be injected entirely in GPU VRAM. To avoid this problem, you can use two options:
- the Ai precisione widget choosing Half precision (this will reduce by 50% the VRAM used so is less probably that frames will be tiled )
- Resize % widget, this can be used tò resize frames before upscale, for example 1920x1080 -> default 70% -> 1344x756 then each frames are upscaled; so for example you can choose 50% It can help
What Is your GPU? :)
